Influence and Effect of Tempering Heat Treatment on the Processing of Composite Noise Reducing Saw Blade
Aiming at the problem of thermal deformation of spot welding in the production process of com-posite noise reducing saw blade,through optimizing the tempering process parameters,adopting the medi-um temperature upper limit tempering and shortening the holding time of the secondary gradient tempering process,the thermal stress was eliminated to the maximum extent after spot welding,thereby improving the flatness and end jump value of the noise reducing saw blade after secondary tempering.For the subsequent grinding and leveling treatment to reduce processing difficulties,while stabilizing the control and ensure the physical quality level of composite noise reducing saw blade.
